AFNetworking POST Method with Nested NSDictionary

Question

I am using AF-networking 2. I want to send Nested NSMutableDictionaryto the server. This is the method I use.

NSMutableArray *arrayRecordSet =[NSMutableArray array];
    for (id contact in _contactGroupArr) {

        ContactGroup *contactGroup=contact;

        NSMutableDictionary *dictGroupDetails=[NSMutableDictionary dictionary];
        [dictGroupDetails setObject:contactGroup.guid forKey:@"guid"];
        [dictGroupDetails setObject:contactGroup.name forKey:@"name"];
        [dictGroupDetails setObject:@"" forKey:@"description"];
        [dictGroupDetails setObject:contactGroup.status forKey:@"isDeleted"];

        NSMutableDictionary *dictContactGroup=[[NSMutableDictionary alloc]init];
        [dictContactGroup setObject:dictGroupDetails forKey:@"contact_group"];

        [arrayRecordSet addObject:dictContactGroup];

    }

    NSMutableDictionary *dictSyncData=[[NSMutableDictionary alloc]init];
    [dictSyncData setObject:arrayRecordSet forKey:@"recordset"];
    [dictSyncData setValue:@"2014-06-30 04:47:45" forKey:@"last_sync_date"];

    NSString *getPath = [NSString stringWithFormat:API_SYNC_CONATCTGROUP];

    [self POST:getPath parameters:dictSyncData
       success:^(NSURLSessionDataTask *task, id responseObject) {

           NSLog(@"%@",responseObject);
       }
       failure:^(NSURLSessionDataTask *task, NSError *error) {
           NSLog(@"%@",error);
       }];

But a server expecting Json format,

Array
(
    [last_sync_date] => 2014-06-30 04:47:45
    [recordset] => Array
        (
            [0] => Array
                (
                    [contact_group] => Array
                        (
                            [guid] => y37845y8y
                            [name] => Family
                            [description] => Family members
                            [isDeleted] => 0
                        )

                )

            [1] => Array
                (
                    [contact_group] => Array
                        (
                            [guid] => gt45tergh4
                            [name] => Office
                            [description] => Office members
                            [isDeleted] => 0
                        )

                )

        )

)

But my code sends this wrong format

Array

    [last_sync_date] => 2014-06-30 04:47:45

        (

                            [description] =>

                        (

                )

            [10] => Array
                (
                    [contact_group] => Array
                        (
                            [isDeleted] => 1
                        )

                )

            [11] => Array
                (
                    [contact_group] => Array

                        )

                )

        )

)

But I checked NSMutableDictionary. Right. Because I manually create a string NSJson. It will give the correct format. I am trying to create the wrong json format.

I am doing my best. But still I have a problem.

EDIT

Server is expecting json

{  

    "last_sync_date": "2014-06-30 04:47:45",

    "recordset": [

        {

            "contact_group": {

                "guid": "y37845y8y",

                "name": "Family",

            } 

        },

        {

            "contact_group": { 

                "guid": "gt45tergh4",

                "description": "Office members",              

                "isDeleted": 0        

            } 

        } 

    ]

}

Answer 1

it looks like you should warp the dictionary contact_groupin another dictionary. Try something like this.

int index = 0;

for (id contact in _contactGroupArr) {

        ContactGroup *contactGroup=contact;

        //level 1
        NSMutableDictionary *dictGroupDetails=[NSMutableDictionary dictionary];
        [dictGroupDetails setObject:contactGroup.guid forKey:@"guid"];
        [dictGroupDetails setObject:contactGroup.name forKey:@"name"];
        [dictGroupDetails setObject:@"" forKey:@"description"];
        [dictGroupDetails setObject:contactGroup.status forKey:@"isDeleted"];

        //level 2
        NSMutableDictionary *dictContactGroup=[[NSMutableDictionary alloc]init];
        [dictContactGroup setObject:dictGroupDetails forKey:@"contact_group"];

        //level 3
        NSMutableDictionary *dictArry=[[NSMutableDictionary alloc]init];
        [dictArry setObject:dictContactGroup forKey:[NSString stringWithFormat:@"%d",index]];

        [arrayRecordSet addObject:dictArry];

        index ++;

    }

, 3, dictContactGroup NSMutableDictionary NSMutableDictionary dictArry, - JSON .

    [0] => Array
    (
       [contact_group] => Array
         (
            [guid] => y37845y8y
            [name] => Family
            [description] => Family members
            [isDeleted] => 0
         )

    )
